Description

A motorcycle mounting plate forming mold

technical field

The utility model belongs to the field of stamping die design, in particular to a forming die for a motorcycle mounting plate.

Background technique

Stamping dies can be called cold stamping dies, also commonly known as cold stamping dies. Stamping die is a relatively special process equipment, which processes materials during the cold stamping process, and finally processes them into parts or semi-finished products. Wherein the material can be metallic material or non-metallic material. Stamping is a method of pressure processing, which is carried out at room temperature. A mold is installed on the press to apply pressure to the material, so that the material is separated or plastically deformed, and then the required parts are obtained. The processing of a plate often has to go through multiple stamping processes such as blanking, punching, drawing, and flanging. If a stamping die is designed for each process, not only the cost is high, but also the processing efficiency of the part will be seriously affected. .
